AZ23C47-G3-08

Overview

The AZ23C47-G3-08 is a dual common anode silicon planar Zener diode array from the Vishay AZ23-G series, housed in a SOT-23 surface-mount package. It features a nominal Zener voltage of 47 V with a ±5% tolerance and a test current of 2 mA. The device has a maximum dynamic resistance of 97 Ω at the test current and a reverse leakage current of 50 μA at 42 V. It operates within a temperature range of -55 °C to +150 °C and dissipates up to 300 mW on an FR-4 board.

Feature Summary

• Dual common anode configuration for space-efficient circuit designs
• Graded Zener voltages according to the international E24 standard
• ESD capability exceeding 8 kV via human body model and 800 V via machine model

Applications

• Voltage reference circuits requiring dual independent references
• Overvoltage protection for sensitive electronic components
• Clamping applications in signal processing paths

Procurement Notes

Verify the specific ordering code suffix against the manufacturer's documentation to confirm the reel size and minimum order quantity requirements. Ensure that the component meets RoHS compliance standards as defined by the supplier. Cross-reference the datasheet revision date to validate the electrical parameters before finalizing procurement specifications.

Selection Notes

Select this component when a dual common anode topology is required within a compact SOT-23 footprint. The ±5% tolerance suits general-purpose regulation tasks where tighter precision is unnecessary. Evaluate the thermal resistance characteristics if operating near the upper limits of the specified ambient temperature range.

Part Context

This part belongs to the AZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of Zener voltages from 2.2 V to 75 V in both 5% and 2% tolerance grades. The 'C' designation indicates the standard 5% tolerance grading used in this specific part number.

Replacement Considerations

AZ23B47-G3-08 provides the same electrical characteristics but with a tighter ±2% voltage tolerance.
